It looks like the rumors about American Idol judges Mariah Carey and Nicki Minaj hating each other are true. According to TMZ, Minaj snapped and cursed out Carey during a recent audition. After a disagreement over a contestant's peformance, Minaj said:

"I told them, I'm not fucking putting up with her fucking highness over there."

The her in question is apparently Carey. During Minaj's rant, Mariah kept her cool and said...well, it's not clear what she was saying but it sounded calm. Meanwhile, Keith Urban just sits there, thinking who knows what.

Minaj also reportedly threatened to "knock out" Mariah later, although that part isn't on tape. I guess if there was ever a reason to watch American Idol, this is it.

Here's TMZ's transcript of the incident:

Nicki Get this s**t in self control. Get in control. Get in control.
Randy: Settle down, settle down
Nicki: Don't lose your head. Don't lose your head (inaudible). Don't tell me I'm a gangster.
Nicki: (inaudible) every 5 minutes. So every time you patronize me, I'm-ma take it back, and if you've got a f**king problem, handle it.
Nicki: I told them I'm not f**kin' putting up with her f**king highness over there. Figure it the f**k out. Figure it out.
Nicki: I'm not gonna sit here every f**king minute to have you come down and harass me every minute everyday.
